Application is using "autoplug-continue" event to select the appropriate demuxer and "pad-added" signal to link to sink pad of mpegTsMux. During the transmuxing process, the Pipeline is getting stuck . After enabling the gst debug(to level 5), we found that the pipeline is getting stuck when the Multiqueue is emitting either the underrun or overrun signal. I had the following questions regarding the multiqueue/decodebin2 and underrun/overrun 1.  Why does underrun and overrun happen in the multiqueue in this kind of pipeline. 2.  What happens when underrun and overrun happens with respect to decodebin2. ? 3.  What are properties (Like max-size-time, max-size-buffers, max-size-bytes) of decodebin2 or multiqueue that can impact overrun or underrun? . 4.  What should be done by the application when there is underrun or overrun ? Any help/pointers on this would be greatly appreciated.
